{"product_id":"greens-functions-and-ordered-exponentials","title":"Green's Functions and Ordered Exponentials","description":"This book presents a functional approach to the construction, use and approximation of Green's functions and their associated ordered exponentials. After a brief historical introduction, the author discusses new solutions to problems involving particle production in crossed laser fields and non-constant electric fields. Applications to problems in potential theory and quantum field theory are covered, along with approximations for the treatment of color fluctuations in high-energy QCD scattering, and a model for summing classes of eikonal graphs in high-energy scattering problems. The book also presents a variant of the Fradkin representation which suggests a new non-perturbative approximation scheme, and provides a qualitative measure of the error involved in each such approximation. Covering the basics as well as more advanced applications, this book is suitable for graduate students and researchers in a wide range of fields, including quantum field theory, fluid dynamics and applied mathematics.","brand":"Cambridge University Press","offers":[{"title":"Default Title","offer_id":39667970768981,"sku":"9780521443906N","price":97.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2481\/5790\/products\/b590e4f3-123b-4814-81df-e204667ea775.jpg?v=1644272839","url":"https:\/\/smeikalbooks.co.uk\/en-us\/products\/greens-functions-and-ordered-exponentials","provider":"smeikalbooks","version":"1.0","type":"link"}
